Sandmeyer Steel Blog


Sandmeyer is now drilling tube sheets with our QuickMill Annihilator.  This order for a processing equipment manufacturer included 4 tube sheets made of 316L. They were machined all over with an OD bevel prep to  36-3/16” OD – 1-1-4” thick, with (97) 2.381 diameter holes that have a 64 finish and a tolerance of +/-.002.  Holes were drilled and milled to size and tolerance on the Annihilator  to quickly meet our customer’s timeline.
